The VTG 400D and VTG 400DVI video test generators include 34 test patterns for calibrating, testing, and troubleshooting any type of A/V system, including projectors and flat panel monitors, HDTVs, and legacy CRT projectors and direct view displays. Several of the patterns are reversible, and some are variable in video output level. The Extreme Grayscale, Contrast Transfer Function, Multipulse, and other patterns were exclusively created for the VTG 400D and VTG 400DVI. Additional test patterns may be added in the future as part of firmware updates via the Windows® control software.

Included with the VTG 400D and VTG 400DVI is a convenient, user-friendly Microsoft Windows-compatible software application that enhances and expedites set-up, programming, and operation. All functions and features of the VTG 400D and VTG 400DVI are easily accessible, including video and audio test signal selection, programming custom scan rates, Quick Select memory presets, and Scope-Trigger. This software is also essential for implementing firmware upgrades. User settings for the software can be saved to a file.

Video Scan rates are activated by simply viewing a list of available rates, and then double clicking with a mouse. The user can obtain comprehensive data relevant to any rate, including horizontal and vertical frequencies, active picture resolution, total picture resolution, horizontal and vertical sync pulse width, and much more. Up to 180 additional custom scan rates can be created by entering new data into the software, copying and then editing existing rates, or importing from a file. Any rate can be exported to a file.

Video Setup Application Any test pattern is activated by selecting from a list with icons depicting the patterns. Depending on the test pattern, the video level is adjustable, and the pattern reversible. Other software controls duplicate the VTG 400D and VTG 400DVI main panel functions, such as selective RGB color channel output and the Auto Sequence and Screen Saver modes.

Scope-Trigger The software takes Scope-Trigger functionality to a new level of ease and convenience. All of the user controls from the VTG 400D and VTG 400DVI main panel are duplicated, but the software adds the convenience of positioning the Scope-Trigger Application Scope-Trigger cursor anywhere within the video image by pointing and clicking. By clicking outside of the active or visible video area, portions of the signal, such as a vertical sync interval, can be examined on the oscilloscope.

Audio Any of the seven available audio test signals are selectable with just the click of a mouse. Output levels for each signal are independently adjustable and simultaneously displayed. The appropriate custom parameters are automatically highlighted for the active signal. Output level units are displayed in dBu or dBV, as well as mV and V. All other audio functions, including muting and selective channel output, Audio Setup Application are easily within access. VTG 400D Audio Test Signals

The VTG 400D and VTG 400DVI feature comprehensive and intuitive professional-grade audio test generators. Seven reference test signals are available that are fully programmable, including frequency, amplitude - output level, and additional parameters. Ideal for use with testing, calibrating, and commissioning high performance audio products and systems, the VTG 400D and VTG 400DVI deliver less than 0.008% THD + noise at +6 dBu for a clean, crisp audio signal reference with no interference from the internal power supply and video test generator. The VTG 400D and VTG 400DVI also deliver frequency response from 20 Hz to 20 kHz, and output test signals

Audio Levels between -72 dBu and +6 dBu, for full Signal Format Range (dBu) Range (dBV) Range (mV) compatibility with professional and Pink Noise -72 dBu to -4 dBu -74 dBV to -6 dBV 0.20 mV to 500 mV consumer audio equipment, and accurate Polarity Test -72 dBu to -14 dBu -74 dBV to -16 dBV 0.20 mV to 158 mV signal generation at microphone level. All other signal types -72 dBu to +6 dBu -74 dBV to +4 dBV 0.20 mV to 1.6 V

Audio level units are specified in dBu and dBV, as well as mV. For all test signals, the level is adjustable in 1 dBu or 1 dBV increments. The VTG 400D and VTG 400DVI output balanced audio on an XLR connector, and unbalanced audio on 3.5 mm mini jack. The VTG 400D also outputs unbalanced audio on RCA. The audio is delivered as mono to either or both of the left and right channels. User-friendly menus and dedicated audio buttons facilitate quick set-up and access to test signals and their parameters.

White Noise • White noise is a randomly generated audio signal – or noise – with equal energy at every frequency. • This test signal spans between 20 Hz and 20 kHz. The output level is variable from -72 dBu to +6 dBu, -74 dBV to +4 dBV. • White noise is used in audio level measurement and equipment calibration.

Pink Noise • Pink noise is a variant of white noise with equal energy at every octave. It is the result of passing white noise through a 3 dB per octave low pass filter. • This test signal spans between 20 Hz and 20 kHz. The output level is variable from -72 dBu to -4 dBu, -74 dBV to -6 dBV. • Pink noise is used in testing and calibrating loudspeakers and sound systems, as well as analyzing and equalizing the acoustical characteristics of room environments.

Sine Wave • Sine waves are periodic, oscillating waveforms represented as sine curves and are elementary components of sound. •  The VTG 400D and VTG 400DVI generate sine waves with programmable amplitude between -72 dBu and +6 dBu, -74 dBV and +4 dBV, and frequency specified between 20 Hz and 20 kHz in 1/12 octave steps. • Sine wave signals are used in testing and measuring the frequency response and distortion of audio products, as well as crosstalk between the left and right channels. VTG 400D Audio Test Signals

Square Wave • Square waves are waveforms with a 50% duty cycle and no DC offset, and are characterized as rectangular-shaped waveforms. • The frequency can be generated from 20 Hz to 5 kHz in 1/12 octave steps. The output level is variable from -72 dBu to +6 dBu, -74 dBV to +4 dBV. Because square waves can damage equipment if played at high levels, the VTG 400D and VTG 400DVI can be set to automatically attenuate the output level to -40 dBu whenever square wave output is selected. • Square waves are usually for testing DC response stability in audio electronics.

Swept Sine Wave • A swept sine wave test signal is a continuous sine wave frequency progression that sweeps between two values. • The VTG 400D and VTG 400DVI offer considerable flexibility in programming swept sine waves. The starting and ending frequencies can be any value between 20 Hz and 20 kHz in 1/12 octave steps. The sweep can progress from the lower to the higher frequency value, or vice versa, with a logarithmic or linear progression. Furthermore, the duration of the sweep is selectable among 15 time intervals between 1 and 120 seconds. The output level is adjustable from -72 dBu to +6 dBu, -74 dBV to +4 dBV. • Swept sine waves are used when testing loudspeaker and crossover defects as well as mechanical vibration sources in the room. They are also effective in measuring and testing room acoustics.

Polarity Test • A polarity test signal is a positive phased pulse with duration of 1 ms and 0.1% duty cycle and 1 s intervals between pulses. • The output level is limited between -72 dBu and -14 dBu, -74 dBV and -16 dBV. • The polarity test signal is useful in determining proper polarity in wiring connections for audio electronics and loudspeakers.

Sine Wave Burst • The Sine Wave Burst generates a sine wave of a specified frequency that is gated on and off for fixed intervals. • The VTG 400D and VTG 400DVI allow for adjustment of the burst interval – the total number of cycles in each repeating period, and the burst on duration – the number of cycles in the interval when the sine wave is turned on. The output level is adjustable from -72 dBu to +6 dBu, -74 dBV to +4 dBV. • Sine wave bursts are used in testing the transient response of audio systems. VTG 400D Specifications
